FILLING END IIOLDEILFOR FILLING-.REPLENISHING LOOMS.

Application filed Apr-i1 24, 192B. $eria1 No. 101,308.

This invention relates particularly to a cross filling end holder for the filling feeder or magazine of a. filling replenishing loom of the well-known Northrop type wherein the supply of fresh filling carriers is contained in a rotatable feeder or magazine. In this type of mechanism, the filling feeder usually has at its outer end a bcll-like circular plate over which the filling ends extending from the filling carriers mounted in. the feeder or magazine are. led and secured at their ends to a centrally supported end holder.

A very substantial amount of filling is wasted by the operatives when placing the fresh filling carriers in the feeder or magazine in attaching the filling ends to the end holder. Usually the ends are drawn otl' much longer than necessary and then wound a number of times around the end holder. This waste is particularly undesirable in the case of expensive yarns such as silk and artificial silk.

The object of the present invention is to provide a simple and eflicient construction of end holder intei which the filling end may readily be directed and by which it may be clamped with a minimum amount of waste and without requiring any particular attention on the part of the operative.

In the ordinary types of filling end holders, the yarn is wound around the end holder until a large mass accumulates and this mass has to be pulled or cut oft, requiring the operatives time and wasting a large amount of yarn.

The object of the present invention is further to provide a construction of end holder upon which it is unnecessary. to wind the filling ends and thus eliminating the accumulation of amass of filling which has to be removed and wasted.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

In the drawings:

Fig. 1 is a vertical diametrical section of a portion of a filling feeder with an end holder embodying a preferred form of the present invention mounted therein Fig. 2 is an end view of the end holder.

Fig. 3 is a detail partially in vertical section :of the end holder shown in Figs. 1 and 2.

The filling feeder or magazine of the usual Northrop type of automatic filling replenishing loom has at its outer end the bell-like circular plate 1 having a central. hub 2. The filling ends extend from the filling carriers in the feeder or magazine over the periphery of this plate and are brought radially to the end holder to which they are secured In the preferred form of the present invention illustrated, the end holder comprises a shank 3 having at its inner end a reduced port-ion 4; fitting an aperture in the hub 2 and held rigidly in place therein by a set screw 5. At its outer end the shank is formed to present a dome-shaped head. 6, the outer surface 7 of which is therefore convex. The shank and head may be of metal.

A stud 8 is mounted axially in and projects from the shank 3. F or that purpose the stud is shown as screw-threaded at its inner end into the shank 3 and as locked in place by a set screw 9 extending transversely through the shank and abutting the stud. In the construction shown, this stud at its outer end is provided with an enlarged head. 10.

A pair of disks having opposed convex surfaces are mounted on the stud and pressed yieldingly together. In the construction illustrated, the inner disk 11 fits into a recess in' the head 6 and has an outwardly pro. jecting sleeve portion 12 and the outer disk 13 is mounted on this sleeve portion. These disks are preferably made of porcelain or some vitreous material to present smooth, hard-wearing surfaces. The inner disk 11 is held firmly in engagement with the head 6 by screwing the stud 8 into the shank, a rubber washer let being seated between the end of the sleeve 13 and the head 10.

The disks are shown as yieldingly pressed together by a helical spring 15 surrounding the stud and abutting at one end a collar 16 adjustably secured by means of a set screw 17 to the head 10 of the stud and abutting at the other end a metal washer 18 placed against the disk 13.

It will be seen that the inner disk 11 forms in effect a part of the head 6 and that the surface 7 of this dome-shaped head merges into the convex surface of this disk ll, although for convenience the disk 11 is, in the preferred form illustrated, shown as a part separate from the head. This convex surface of the head and inner disk serves to direct each filling end, as it is drawn radially inward from the periphery of the plate 1 by the operative, in between the disks where it is clamped and held by the spring ressure.

lit will therefore be seen that all the operative has to do is to take hold of the extreme end of each filling end and carry it radially inward from the periphery of the plate 1 and swing it or slide it along the guiding surface of the dome-shaped head until it is clamped between the spring pressed disks. This requires no skill on the part of the operative and is practically an automatic movement so that wastage of filling is reduced to a minimum.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

1. A fillin end holder for the filling feeder of a filling replenishing loom comprising a shank having a dome-shaped head, a stud mounted axially in, and projecting from, the shank, and a pair of spring pressed disks having opposed convex mounted on the stud with the surface of the dome head merging with that of the inner disk thus to direct a filling end carried over the head between the disks ,to be clamped thereby.

2. A filling end holder for the filling feeder of a filling replenishing loom comprising a shank having a dome-shaped head, a stud mounted axially in, and projecting from, the shank, a pair of vitreous disks having opposed convex surfaces mounted on the stud with the surface of the dome head merging with the surface of the inner disk, a collar mounted on the end of the stud, and a spring interposed between the collar and the outer disk and acting to press the disks together, whereby a filling end carried over the head is directed between" the disks to be clamped thereby.

In testimony whereof, I have signed my name to this specification.
